An electromagnetic interference (EMI) shielding filter includes a conductive pattern for shielding electromagnetic waves; and blackened layers formed on a surface of the conductive pattern. The electromagnetic interference (EMI) shielding filter is manufactured by preparing a base film; forming on the base film a first blackened layer, a conductive layer, and a second blackened layer in sequence; and patterning the first blackened layer, the conductive layer, and the second blackened layer by using a same mask, and forming on front and rear surfaces of an EMI shielding layer a conductive pattern comprising the first and second blackened layers.
